Downfall

# Downfall Performance Analysis: AMD Ryzen 7 7700 + AMD Radeon RX 7800 XT

The measured frame rates for this combination in Downfall reveal a system that scales predictably across resolutions, with the GPU becoming the dominant constraint at 4K while the CPU's strong single-thread performance keeps 1080p frame rates exceptionally high. At 1080p Low, the combo delivers 280.9 FPS, while 4K Ultra drops to 54.5 FPS — a spread that highlights how the horror title's visual demands escalate with each setting tier. The data shows a pairing that excels at high-refresh 1440p gaming, but the Ultra preset at 4K pushes the graphics card to its limits, suggesting that users targeting 4K should consider the High or Medium presets for smoother gameplay.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but not uniform across presets. At Low settings, 1080p yields 280.9 FPS, dropping to 124.6 FPS at 4K — a reduction of 156.3 FPS (55.6%). At High settings, the drop is from 187.3 FPS at 1080p to 82.4 FPS at 4K, a 104.9 FPS reduction (56.0%). The Ultra preset shows the most dramatic scaling: 117.9 FPS at 1080p falls to 54.5 FPS at 4K, a 63.4 FPS decrease (53.8%). Interestingly, the percentage drop remains remarkably consistent across all presets, hovering around 54-56%, which indicates that resolution scaling is primarily GPU-bound rather than settings-dependent.

This consistency suggests that the RX 7800 XT's 16 GB of GDDR6 memory and 624.1 GB/s bandwidth are sufficient even at 4K, as the frame rate penalty comes from pixel throughput rather than memory capacity. The GPU's 96 ROPs and 233.3 GPixel/s pixel rate become the limiting factor at higher resolutions, while the CPU's role diminishes. At 1440p, the scaling from 1080p shows a similar pattern: Low drops from 280.9 to 197.4 FPS (29.7% reduction), while Ultra drops from 117.9 to 85.7 FPS (27.3% reduction). The smaller percentage drop at 1440p versus 4K confirms that the GPU has more headroom at this resolution, making it the sweet spot for this combination.

GPU Role

The Radeon RX 7800 XT's specifications explain much of the observed behavior. With a boost clock of 2430 MHz and a game clock of 2124 MHz, the GPU maintains high throughput across all tested settings. The 16 GB GDDR6 memory on a 256-bit bus provides 624.1 GB/s bandwidth, which appears adequate for Downfall's demands even at 4K Ultra, where the 54.5 FPS result is more likely constrained by the 3840 shading units and 60 RT cores rather than memory throughput. The GPU's 37.32 TFLOPS FP32 performance translates to strong rasterization, yet the Ultra preset at 4K still pushes the card to its limit.

The difference between Low and Ultra at the same resolution illustrates the GPU's workload scaling. At 1080p, Low produces 280.9 FPS versus 117.9 FPS at Ultra — a 163 FPS gap (58.0% reduction). At 4K, the gap narrows to 70.1 FPS (124.6 vs 54.5, a 56.3% reduction). This narrowing suggests that at 4K, the GPU is already near its saturation point, so the relative cost of Ultra settings becomes less pronounced in absolute terms but still significant in percentage. The GPU's 76th percentile ranking among all GPUs, with an average benchmark score of 32619, places it as a solid mid-to-high performer, though its nearest rivals (AMD FirePro S9300 X2 at 32540, 0.2% delta; NVIDIA P104-100 at 32747, -0.4% delta) show that it sits in a tightly contested performance band.

How This Combo Ranks

This specific CPU-GPU combination ranks 645th out of 1741 tested combos in Downfall, placing it in the 63rd percentile of all pairings. This ranking is notable because the individual components rank higher in their respective categories: the Ryzen 7 7700 sits at the 91st percentile among CPUs, while the RX 7800 XT is at the 76th percentile among GPUs. The combined ranking being lower than either component's individual percentile suggests that Downfall may not fully utilize the CPU's capabilities, or that the game's engine favors certain hardware configurations over others.

The combo's position in the middle-upper tier of tested systems indicates that while this pairing delivers strong frame rates, there are faster combinations available. The CPU's nearest rivals — the AMD Ryzen 9 7940H (0.1% higher average score), AMD Ryzen AI 9 365 (0.5% higher), Intel Core i9-13905H (0.6% lower), and Intel Core Ultra 5 235T (1.2% higher) — all cluster within a narrow performance band, suggesting that CPU choice has limited impact on this game's results. Similarly, the GPU's rivals (AMD FirePro S9300 X2 at 0.2% higher, NVIDIA P104-100 at 0.4% higher, NVIDIA T600 Mobile at 0.7% higher, AMD FirePro S10000 at 0.7% lower) indicate that small benchmark differences translate to minimal real-world FPS variation in Downfall.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional frame rates across all presets. Low settings produce 280.9 FPS, Medium reaches 228.6 FPS, High manages 187.3 FPS, and Ultra still achieves 117.9 FPS. These numbers indicate that at 1080p, the CPU and GPU combination is rarely stressed, with even the most demanding preset maintaining well above 100 FPS. The 163 FPS difference between Low and Ultra at this resolution shows that graphical settings have a substantial impact, but the baseline performance is so high that all presets remain playable.

Moving to 2560x1440, the frame rates remain strong but show the expected decline. Low produces 197.4 FPS, Medium 162.2 FPS, High 134.5 FPS, and Ultra 85.7 FPS. The gap between Low and Ultra narrows to 111.7 FPS, reflecting the increased GPU workload at this resolution. The High preset at 1440p delivers 134.5 FPS, which is close to the 1080p Ultra result of 117.9 FPS, suggesting that the GPU can handle a resolution increase with a modest settings reduction.

At 3840x2160, the GPU's limits become apparent. Low yields 124.6 FPS, Medium 101.4 FPS, High 82.4 FPS, and Ultra 54.5 FPS. The Ultra preset at 4K dips below 60 FPS, making it borderline for smooth gameplay on standard 60 Hz displays. The Medium preset at 101.4 FPS and High at 82.4 FPS both remain playable, but users seeking 4K Ultra will need to accept frame rates below the 60 FPS threshold. The progression from 1080p Low (280.9 FPS) to 4K Ultra (54.5 FPS) represents a 226.4 FPS total drop, demonstrating the full range of this combo's performance envelope.

CPU Role

The AMD Ryzen 7 7700's 8 cores and 16 threads, running at a base clock of 3.80 GHz and boost of 5.30 GHz, provide substantial processing power. Its Cinebench R23 multi-core score of 29302 and single-core score of 4136 indicate strong all-around performance, with the single-thread result being particularly relevant for Downfall's engine. The CPU's 91st percentile ranking among all CPUs, with an average benchmark score of 40468, places it well above the median, yet the measured FPS data shows that at 4K, the GPU becomes the bottleneck.

The PassMark single-thread score of 4063 and 3DMark single-thread score of 1049 suggest that the CPU's per-core performance is sufficient to drive high frame rates at lower resolutions. At 1080p Low, the 280.9 FPS result indicates that the CPU can feed the GPU with enough draw calls to maintain very high frame rates, but the game's horror genre may not require complex physics or AI calculations that would stress all 16 threads. The CPU's 65 W TDP and Zen 4 architecture on a 5 nm process contribute to its efficiency, but the benchmark data shows that the 7700's nearest rivals — all within 1.2% of its average score — deliver nearly identical gaming performance in this title.

Settings Recommendations

The measured data provides clear guidance for optimal settings based on resolution targets. At 1080p, the Ultra preset at 117.9 FPS is the best choice, as it delivers the highest visual quality while maintaining frame rates well above the 60 FPS threshold. Users with high-refresh monitors (144 Hz or above) could consider High at 187.3 FPS or Medium at 228.6 FPS for competitive advantages, but the visual fidelity loss may not be justified given Ultra's playable frame rate.

At 1440p, the High preset at 134.5 FPS offers the best balance of visual quality and performance. Ultra at 85.7 FPS remains playable, but the 48.8 FPS drop from High to Ultra represents a significant visual return on investment. Medium at 162.2 FPS is suitable for users prioritizing frame rate over fidelity, while Low at 197.4 FPS is reserved for maximum performance scenarios. At 4K, the Medium preset at 101.4 FPS is the recommended choice, as it provides smooth gameplay while maintaining reasonable visual quality. High at 82.4 FPS is also viable, but Ultra at 54.5 FPS falls below the 60 FPS threshold and may result in noticeable stuttering. Low at 124.6 FPS sacrifices too much visual detail for the frame rate gain.
